centos， how to get the root

To access the root user in CentOS, you can follow these steps:

1. Open a terminal on your CentOS system.
2. Log in as a user with administrative privileges.
3. Type the following command and press Enter:

   sudo su -

This command will prompt you to enter the password for the current user.
4. Provide the password and press Enter.
5. If the password is correct, you will be logged in as the root user, indicated by a change in the command prompt.

Note: It is generally recommended to use the root user sparingly and only for tasks that require administrative privileges. It's good practice to use a regular user account for day-to-day activities and switch to the root user only when necessary.
